Hi,

Thanks for the reply.

Does anybody  have any other solutions?
Because when i need to do this.. I need to setup an entire new environment with Virtual Servers etc etc.

Greatz,
Mikey

Hi there

I've got several rules.. But non of them are working properly..

"How to detect a DNS Query Reply -> OK"..
This is something i've created a couple of days ago... Doesn't work as it should be.. This detects "all querys".. Even 
when its refused...

I would take the packet capture you have and throw it into wireshark and learn which bytes in the packet you have 
indicate a "Query Reply -> OK" response, and write a rule to detect that sequence of bytes.
